Animal welfare around the world: examining the role the economy has on animal welfare
Contributor(s):: Olivia J. Thornton
Every person has a different perspective from which he or she views animals. For some, an animal is almost human-like; for others, animals are a means to an end; for most people, their beliefs fall somewhere between these two extremes. Animals may be viewed as pets by some and...
Mate choice, maternal investment and implications for ostrich welfare in a farming environment
Contributor(s):: Bonato, M., Cherry, M. I., Cloete, S. W. P.
At present, the ostrich industry is inefficient, on account of being characterised by inadequate egg production, high embryo mortality, poor chick survival and suboptimal growth rates. However, as ostrich farming commenced only in the mid 19th century in South Africa, farmed ostriches have had a...

Review of human-animal interactions and their impact on animal productivity and welfare
Contributor(s):: Idrus, Zulkifli
Humans and animals are in regular and at times close contact in modern intensive farming systems. The quality of human-animal interactions can have a profound impact on the productivity and welfare of farm animals. Interactions by humans may be neutral, positive or negative in nature. Regular...
Growth and Age at Reproductive Maturity of the Carolina Pigmy Rattlesnake, Sistrurus m. miliarius (Reptilia: Serpentes)
Contributor(s):: Kevin Robert Messenger
Growth and age at reproductive maturity are life history attributes that play an important role in the development of proper management strategies. The Carolina Pigmy Rattlesnake, Sistrurus m. miliarius, is one of two dwarf rattlesnake species. The subspecies ranges from eastern NC to nearly the...
The ecology of the peaks of otter salamander (Plethodon Hubrichti) in sympatry with the eastern red-backed salamander (Plethodon Cinereus)
Contributor(s):: Norman Reichenbach, Andrew Kniowski
The Peaks of Otter Salamander, Plethodon hubrichti, is found along a 19 km length of the Blue Ridge Mountains, Virginia, USA, often in sympatry with the Eastern Red-backed Salamander, P. cinereus. In a sympatric area of Bedford County, Virginia, we conducted a mark-recapture study on a 10 × 10 m...
Conservation implications of dietary dilution from debris ingestion: sublethal effects in post-hatchling loggerhead sea turtles
Contributor(s):: Shannon J. McCauley, Karen A. Bjomdal
Ingestion of anthropogenic debris by marine species has been documented extensively; fewer studies have attempted to quantify the sublethal effects caused by debris ingestion. One potential sublethal effect is reduced nutrient gains from diets diluted by consumption of debris. Post-hatchling and...
Breeding for better welfare: genetic goals for broiler chickens and their parents

An investigation into the effect of different protein and energy intakes on model tail chewing behaviour of growing pigs
Contributor(s):: McIntyre, J., Edwards, S. A.
Twenty-four crossbred pigs were housed individually and allocated at 62 kg (S.E.M.=0.81) to one of three diets providing differing daily protein and energy intakes: control (C) 1.42 g CP/MJ DE, fed to provide 2.85 maintenance energy; low protein (LP) 0.76 g CP/MJ DE fed to provide the same daily...
Assessing the effects of a chronic stressor, stocking density, on welfare indicators of juvenile African catfish, Clarias gariepinus Burchell
Contributor(s):: Nieuwegiessen, P. G. van de, Boerlage, A. S., Verreth, J. A. J., Schrama, J. W.
Fish welfare is an area of increasing interest and stocking densities used in commercial aquaculture have been highlighted as a subject of specific welfare concern. The present study assessed how stocking density affects growth performance (final body weight, SGR, FCR), physiological (plasma...
Assessment of acute pain experienced by piglets from ear tagging, ear notching and intraperitoneal injectable transponders
Contributor(s):: Leslie, E., Hernandez-Jover, M., Newman, R., Holyoake, P.
Suckling piglets are routinely identified to assist with their day-to-day management. A total of 120 suckling piglets were used to determine and compare the short-term pain responses to a number of identification methodologies, including: ear notching, ear tagging and intraperitoneal injection...
Behaviour of growing lambs housed on straw or woodchip bedding materials and their preference for floor type
Contributor(s):: Wolf, B. T., Molloy, H. R. B., Trayte, M. J., Rose, M. T.
Straw is widely used as a bedding material for housed sheep, but alternatives are needed in regions where straw is expensive or in short supply. The aim of this work was to compare time budgets, growth and food intake of growing, finishing lambs housed on either woodchip or straw bedding...
Behaviour of juvenile mud crabs Scylla serrata in aquaculture: response to odours of moulting or injured crabs
Contributor(s):: Wall, D., Paterson, B., Mohan, R.
Behaviour of juvenile mud crabs, Scylla serrata (70-90 mm carapace width, CW) were observed in response to odours of moulting and injured conspecifics and food (pilchard) under controlled flow conditions using bioassay technique. This study was undertaken to better understand the role that...
Comparison of the behaviour of Awassi lambs in cafeteria feeding system with single diet feeding system
Contributor(s):: Keskin, M., Sahin, A., Bicer, O., Gul, S.
This study was carried out to compare behavioural activities of Awassi lambs in cafeteria feeding system with conventional feeding (control) that animals fed concentrate. Sixteen, 3-month-old male lambs were housed individually for 42 days. The main effect was on the feeding systems, cafeteria...
Effects of qualitative and quantitative food restriction treatments on feeding motivational state and general activity level of growing broiler breeders
Contributor(s):: Savory, C. J., Lariviere, J. M.
Growing broiler breeder chickens are fed restricted rations to limit body weight at sexual maturity. This experiment tested a proposal (Brouns, F. et al. Applied Animal Behaviour Sciience (1994) 39, 215-223.) that feeding motivation is reduced by using qualitative rather than quantitative food...

Contributor(s):: Sevi, A., Caroprese, M., Annicchiarico, G., Albenzio, M., Taibi, L., Muscio, A.
The aim of the experiment was to compare the welfare and weight gains of artificially reared lambs when gradually separated from their mothers or separated from them early and immediately or gradually moved from maternal to reconstituted milk. Forty Comisana lambs were assigned to a control...
The effects of regular visual contact with human beings on fear, stress, antibody and growth responses in broiler chickens
Contributor(s):: Zulkifli, I., Gilbert, J., Liew, P. K., Ginsos, J.
This study investigated the effects of regular visual contact at various ages on tonic immobility (TI) and heterophil/lymphocyte ratio (HLR) reactions to handling and crating, antibody production, growth performance and feed conversion ratios in commercial broiler chicks. Broiler chicks were...
Behaviour of fast- and slow growing broilers to 12 weeks of age and the physical consequences
Contributor(s):: Bokkers, E. A. M., Koene, P.
Behaviour of broilers up to 6 weeks of age has been studied extensively, but little is known what happens after 6 weeks. Insight in the behavioural abilities after 6 weeks may also yield insight in the period before 6 weeks as the disbalance between motivation and physical abilities is more...
